BG. Series with younger brothers as male leads. either it's a stepbrother, half-brother or bio brother (though I prefer the first two way more).... more>>

If there is a younger brother ML but he is non-virg*n, a playboy or scum, I wouldn't put it down here. I prefer cute virg*n younger brother or the obsessive yandere younger brother trope.

Manga with younger brother ML that I like: Binetsu Kuukan. Game with younger brother ML that I like: Shun from Watajuu. <<less
